Abstract

The utility model relates to a blade fixed structure for a longitudinally cutting sub-die. The blade fixed structure comprises an upper die blade arranged on a longitudinally cutting upper template and a lower die blade arranged on a longitudinally cutting lower template. The cutting edges of the lower die blade and the upper die blade are opposite up and down. The utility model is characterized in that the blade fixing structure further comprises an upper fixing block; a flat groove is opened on the longitudinally cutting upper template; a flat pin is arranged in the flat groove; the lower end of the flat pin is provided with a flat pin hook; the upper fixed block is inserted in the flat groove; the upper end of the upper fixed block is provided with a fixed block hook; the fixed block hook is butted with the flat pin hook; and the upper die blade is fixedly connected with the lower end of the upper fixed block. The blade fixing structure for the longitudinally cutting sub-die has simple and smart structure and can easily adjust the gap between the upper die blade and the lower die blade, thus improving the exchange between the upper die blade and the lower die blade and reducing the machining difficulty of the longitudinally cutting upper template. In addition, the upper die blade is detached more conveniently.

Description

A kind of blade fixing structure of slit sub-die
Technical field
The utility model belongs to the Stamping Die Technology field, relates to the slit sub-die in a kind of air-conditioner fin die, specifically a kind of blade fixing structure of slit sub-die.
Background technology
At present, traditional pipe type heat exchanger is the main heat exchange form of domestic air conditioning, central air-conditioning, car air-conditioner and fan coil.Air-conditioner fin is the vitals in the pipe type heat exchanger.Air-conditioner fin generally adopts the air-conditioner fin die punching press to make, and its production process generally comprises and extends, punching, shutter, flange, abnormal shape are cut, cut on the limit, correcting, rip cutting, feeding and crosscut.The quality that rip cutting operation is wherein finished directly influences the outward appearance of fin product.The rip cutting operation realizes by slit sub-die, slit sub-die is the independent mould that has guider on the air-conditioner fin die, it comprises patrix blade and counterdie blade, the patrix blade directly inserts and is fixed in the groove of offering on the rip cutting cope match-plate pattern, the counterdie blade directly is fixed on the rip cutting lower bolster, and the counterdie blade is relative up and down with the cutting edge of patrix blade.Because the thickness of patrix blade is about 3~6mm, the groove of rip cutting cope match-plate pattern is processed the comparison difficulty, tolerance also is not easy to guarantee, unfavorable condition often appears, in addition because the number of groove is more, generally about 60, if a groove fine finishining is overproof, the quality of whole rip cutting cope match-plate pattern all is affected.The gap that the rip cutting cope match-plate pattern directly has influence on again between patrix blade and counterdie blade is even, and then has influence on the outward appearance of fin product.In order to adjust the gap between patrix blade and counterdie blade, need carry out repair to every cutter, cause the interchangeability of blade also bad, and the dismounting of blade is also relatively more difficult.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of blade fixing structure of slit sub-die of simple and ingenious structure is provided, this structure can make the gap between patrix blade and counterdie blade adjust convenient, improved the interchangeability of patrix blade and counterdie blade, reduced the difficulty of processing of rip cutting cope match-plate pattern, made the dismounting of patrix blade convenient simultaneously.
The technical scheme that provides according to the utility model: a kind of blade fixing structure of slit sub-die comprises the patrix blade that is installed on the rip cutting cope match-plate pattern and is installed in counterdie blade on the rip cutting lower bolster that described counterdie blade is relative up and down with the cutting edge of patrix blade; It is characterized in that: described blade fixing structure also comprises fixed block; Offer flat groove on the described rip cutting cope match-plate pattern, be equipped with cotter pilotage in the flat groove, the lower end of cotter pilotage is provided with the cotter pilotage gib head, and the described fixed block of going up is inserted in the flat groove, and the upper end of last fixed block is provided with the fixed block gib head, this fixed block gib head and the mutual snapping of cotter pilotage gib head; Described patrix blade is fixedly connected on the lower end of fixed block.
The utility model compared with prior art, advantage is: the gap of patrix blade and counterdie blade is easy to adjust, the last fixed block that only needs repair to increase newly during the adjusting play, on increasing newly, carry out mark then on the fixed block, so not only guaranteed the interchangeability of last bottom knife, and dismantled more convenient.Also reduced the processing request of rip cutting cope match-plate pattern in addition,, greatly reduced the processing request of flat groove as long as can join between the flat groove of last fixed block that increases newly and rip cutting cope match-plate pattern.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1, the utility model mainly comprises rip cutting cope match-plate pattern 1, cotter pilotage 2, last fixed block 3, patrix blade 4, counterdie blade 5, following fixed block 6 and rip cutting lower bolster 7.
Offer flat groove 8 on the described rip cutting cope match-plate pattern 1, be equipped with cotter pilotage 2 in the flat groove 8, the lower end of cotter pilotage 2 is provided with cotter pilotage gib head 2a, and the described fixed block 3 of going up is inserted in the flat groove 8, the upper end of last fixed block 3 is provided with fixed block gib head 3a, this fixed block gib head 3a and the mutual snapping of cotter pilotage gib head 2a; Described patrix blade 4 is fixedly connected on the lower end of fixed block 3 by screw; Described counterdie blade 5 utilizes screw to be fixedly mounted on down the upper end of fixed block 6, and counterdie blade 5 is relative up and down with the cutting edge of patrix blade 4; Following fixed block is fixed on the rip cutting lower bolster 7.
After adopting structure of the present utility model, patrix blade 4 is easy to adjust quick with the gap of counterdie blade 5, need not the reconditioning blade during adjustment, has guaranteed the interchangeability of patrix blade 4, counterdie blade 5.
